The utility model relates to an air inlet of a coil-tube type air-conditioning blower with convenient cleaning, in particular a magnetic air inlet of an air-conditioner with convenient cleaning, mainly consisting of an external frame (1), a shutter air door (2) and a filter mesh (3). The filter mesh (3) is attached on the inner side of the shutter air door (2); and the articulation, opening/closing and locking of the external frame (1) and the shutter air door (2) are realized by two attachments (a simple hinge (7) and a magnetic locking device (4)). Only if the shutter air door (2) is pulled lightly, the filter mesh (3) can be taken out easily; and the filter mesh is cleaned without dismounting the air port, so that the cleaning of the filter mesh is very simple and convenient.
